Answer:
1
Step-by-step explanation:
Answer: 5 cm by 10 cm gives an area of 50 cm^2
To do this draw a parallelogram and start by labeling the base as 10 cm. If 10 cm is the base, then the height needs to be 5 cm.
To find the area, multiply the base times height.
This will give you: 5 x 10 = 50 which is less than 60.
